Poll: Have you ever experienced any brake issues on the Track in your 370?
 

I'm just curious how many people have ever experienced brake related issues on the track in their Z.

Have you ever experience complete Brake Failure? ABS messing up, etc?

I don't know how useful the poll results will be unless you qualify things a bit. Sport vs non-sport brakes. Whether fluid was upgraded to e.g RBF600 (because boiling stock brake fluid is pretty normal on any car), whether pads were upgraded, etc. I voted for the ABS option because I did have ABS Ice-Mode issues on my stock Sport calipers (with various pads). Once you know what it is and how it feels, it's not that hard to drive around it by lifting and reapplying brake pressure, and putting a stronger pad up front than in the rear helps reduce it a lot as well. Never had any issues since the upgrades to the Stillen/AP BBK (the first version, not the RadiCal one) + Carbon-Lorraine RC6E pads.

Agree. It's not an easy question because many people would do research and fix potential problems before ever setting foot on a track.
Just curious though.

Yep, thats what I did, I and I would hope others would do the same. The cost for upgrading the pads and fluid is negligible when you think of the potential cost of having no brakes approaching a turn at 120. Oh and I had no issue with loss of brakes btw though I would assume this pole if for people still on the stock setup so I didn't vote.

You can't select more than one!

Sorry about that. I guess if you've had both total brake failure and ABS issues, pick total brake failure since it's the more severe.

Good point. I was assuming stock, my assumption is no one has had an issue on upgraded pads and brake fluid. That would be interesting to know for sure...

^ My mention of ABS Ice-Mode issues is with upgraded pads + fluid. That issue is intrinsic to the ABS (+ calipers and other hardware) on our car.

On the other hand, I would hope nobody's seeing complete brake failure on-track like boiled fluid with RBF600.

I've had some odd hiccups with the brakes here and there. Twice now towards the end of a track day I think theyve overheated on a road course and for some reason it feels like the front right caliper locks up or doesn't brake quite as well. This is with motul rbf600, z1 SS lines, hawk hp+ pads, stillen ducting, and z1 2 piece front rotors. This last AutoX I was having braking problems but I think my pads are shot. Have to check em out. I have carbotech Xp10 f 8 r on order anyways.

I can feel my castrol srf boiling after one hard session

i have sport brakes, i had a ice mode incident once during a panic stop on track when a car in front of me braked on a section of the track that no braking should occur

I used to have a lot of ABS type problems. Honestly the MX-72 pads cleared up a lot of them. They are pretty few and far between now. Streets of Willow CCW going into 1 can trigger it. And sometimes the hairpin at ACS, but besides that it doesn't seem to happen too much anymore.

first track day, sport brakes, HP+ pads and Valvoline synthetic fluid, on a very short track, 1.2 miles, 12 turns, Little talladega.
1200 miles on car, first time out, taking it easy, boiled the fluid, wore the brakes down to backing plates and ruined the rotors. When the fluid boils, it goes very fast. Halfway around the track they felt soft, so I backed off and coasted to the pits and it took me about 50 yards to stop from 10 mph.

Now I have stoptech trophy brakes with titanium backing plates and stillen cooling kit and have zero issues

Has anyone running the better fluid that doesn't have the boiling problem put a laser tempature reader against your brake master cylinder after a day of tracking it?
Curious how close the margin of saftey is. Is the fluid getting up to 400 degrees, 500, 599?

I think the boiling happens down in the caliper where the heat is greatest. Some heat will travel up the fluid, but I'd suspect the stuff up in the master cylinder is significantly cooler (probably more affected by engine bay heat than caliper heat).

Boiling happens in the caliper, heat goes from pad to pad backing plate to pistons to fluid.
